What is wrong with this code I am stuck


.balls {
border-radius: 50%;
background: linear-gradient(
position: fixed;
width: 50px;
height: 50px;
margin-top: 50px;
animation-name: bounce;
animation-duration: 2s;
animation-iteration-count: infinite;
#ball1 {
#ball2 {

@keyframes bounce {
0% {
top: 0px;
100% {
top: 249px;


I see nothing particularly wrong with this code, what’s the problem are you dealing with?

I don’t know, I keep trying to submit it and it won’t let me go any further in the lesson; it’s like that for the last 4 :triumph:

Please post a link to the challenge so we know which one it is.


Your code passes the tests for me. Which browser are you using?

I am currently using Microsoft Edge

If you can, try a different browser. I think the challenges work best in Chrome.

Little wonder, Microsoft edge has compatibility issues, you can always check with chrome or firefox to enjoy your experience
